[FIX] purchase_stock: propagate PO line sequence to stock moves

The default order of the picking moves generated from a purchase order should be the same order as the purchase order lines.

Steps to reproduce:
- Create a purchase order with several purchase lines.
- Change the order of the purchase lines.
- Confirm the purchase order.
  => The moves of the picking don't maintain same order as set before.
